A passenger of a cable car looks out, as another cable car is seen, on the route from La Paz to El Alto, in La Paz, July 23, 2015. Bolivia already has the largest urban cable car system in the world. Now the booming country is tripling the size of the network and will soon have nine lines whizzing above the administrative capital of La Paz. Picture taken July 23. REUTERS/David Mercado
